If you're into atomic physics and getting a feel for the intricate structure of the basic processes, the best find I had recently is this MIT course by Wolfgang Ketterle. The first lecture is an informal overview, and he gives vivid and detailed descriptions of the phenomena they can create and control now, like why we see different kinds of thing happening at very low temperatures: the atoms are moving past each other so slowly that it gives their wavefunctions time to overlap and interact, using intersecting lasers to create arrays of dimples in the electromagnetic field to draw in and hold single atoms, this kind of thing. It gives a more tangible insight into the quantum aspects of matter that can otherwise seem inscrutable

He also got the Nobel prize in the 90s for making a Bose-Einstein condensate iirc.

Yeah, soon after I posted this it became clear it's nonsense, a few people in the thread have referred to studies that trees underneath the landslide have been carbon dated to 9400BP, while the book this article's based on claims 5500BP for an "impact"

I mainly posted this because I was beguiled by the images of the disk. I hadn't seen it before, so even these shoddy images were impressive, with the circular form, radially arranged characters and lines looking both ancient and technical. Would you recommend a source for some proper information on it? I'm curious about what it says. Googling I keep coming up with rehashings of this meteor story from websites with "Atlantis" in their names and suchlike.

Very perspicacious remark that it's more likely than five or four... are you an astronautical engineer by any chance?

But I'm wondering about such shallow angles - wouldn't it bounce off the atmosphere or somesuch? Perhaps it's just about possible somehow: just imagine firing a kilometre of rock from a mountain at a six degree angle with enough velocity to get it into orbit, but in reverse.

The plot thickens: a commenter here posted this link, which indicates Ötzi might have been roped in to this story in quite an imaginative way:

"Despite this new evidence, curiously in 2008 the impact hypothesis was revived by some pseudoscientists in connection to supposed observations of a meteorite by the Sumerians or to explain the death of the Iceman as a human sacrifice to prevent a nuclear winter after the impact."

Unfortunately the sciforums link to discussion of the pseudoscientists is dead

Yeah, it was quite a compelling story, and it's at least a genuinely beautiful and intriguing tablet. The author Hempsell does have some talent though, in seemingly getting a reputable university to publish his book... I'm thinking he was quite canny in finding this attractive untranslated tablet with little else written about it, and then employing enough knowledge about a combination of different subjects (ancient Sumerian, asteroid orbits, Alpine geology) that no single reviewer was able or motivated to properly evaluate all the arguments. Or he just had a friend at the press.
